What is the difference between virgin and regenerated Polyester Staple Fiber?

VNPOLYFiber uses regenerated polyester fiber fills for many of its products. Environmentally friendly, cost-effective, and safe, the regenerated polyester fiber is made from recycled plastic water bottles and performs equally as well as 100% virgin polyester for fills.

There is no difference in quality, the recycled fibers are the same as the virgin polyester but they are made out of post-consumer plastic bottles.

You may ask: Is it synthetic or is it down? Thanks to today’s cutting-edge technologies, it may be tough to tell the difference. Commonly known as “down alternatives”, Vnpolyfiber polyester fills are less expensive than down, but share similar performance benefits. From polyester batting to fluffy cluster fibers, these fills are ideal for creating easy-to-care-for, allergy-free bedding solutions.

• THE ENERGY NEEDED TO MAKE THE RPET IS LESS THAN WHAT IS NEEDED TO MAKE THE VIRGIN POLYESTER
• RECYCLING PET TO CREATE THE FABRICS PREVENTS IT FROM GOING TO LANDFILL
• USING MORE RECYCLED POLYESTER REDUCES OUR DEPENDENCE ON PETROLEUM AS THE RAW MATERIAL FOR OUR FABRIC NEEDS

Let’s first talk about Virgin Polyester Staple Fiber

Virgin Polyester Staple Fiber (Virgin PSF)

Virgin Polyester Staple Fiber a synthetic man-made fiber that is manufactured from PTA & MEG through polymerization performed at a high temperature and pressure
After the spinning and drawing process, the polymer becomes staple fibers when cut short into the form of cotton or filament yarns when made into the form of yarn.

Staple fibers are widely used for industrial use as well as for clothing.
They are not only used for filling clothing, bedding, and furniture in the form of cotton or spinning after twisting cotton into yarn but they are also fabricated into non-woven fabrics through compression and used for a wide range of applications, including automobile, construction, furniture, sanitary materials, and agriculture, gradually expanding their scope of application.

Virgin Polyester Staple Fiber Production Process

Application:

Automobile, Furniture, Sanitary products, Cleaner Filter, Various non-woven fabrics, Civil/construction materials, Clothing Sport wear, Premium padding, Innerwear, Bedding Accessory Interior

Polyester benefits

• Polyester fills are typically less expensive to produce than down and feather or microfiber fills making them practical and cost-efficient
• Polyester fills are hypoallergenic and are ideal for products designed for allergy-sensitive sleepers
• When it comes to easy maintenance, polyester fills are tough to beat and easy-to-care-for
• Adding a silicon finish to polyester fills provides a slick hand similar to down and feather fills

Recycled Polyester Staple Fiber (PSF)

How is recycled polyester different from virgin polyester?

As said earlier, Because the recycling process reconstitutes the fiber on a molecular level, there is no difference between recycled polyester and virgin polyester. Performance and durability, benefits, including high strength and functional versatility of recycled polyester is the same as traditional polyester but with a lower environmental impact.

Why is recycled polyester better?

1. Recycled polyester doesn’t require new petroleum to create, lowering the demand for new petroleum extraction and reducing our overall carbon footprint.
2. Producing recycled polyester is better for the climate, creating 75% less CO₂ emissions than virgin polyester.
3. By providing a use for post-consumer and post-industrial

Advantages of regenerated polyester staple fiber:

– Warm keeping: The hollow polyester staple fiber is lighter by 20% than ordinary fiber with its hollow Construction. It makes no air convection in fiber to keep warm. It can keep the body warm by wrapping warm air and isolating cold air. The fiber is light and good in warm-keeping.
– Good hygroscopicity: Hollow polyester staple fiber can discharge the moisture quickly in the body skin and keep dry and warm, reduce the uncomfortable sticky feeling with its advantages of special wicking effect and large surface.
– Soft feeling in the hand, good fall: It bright soft, and comfortable feeling in hand to touch the hollow polyester staple fiber fabric. Compared with the daily heavy thermal fabric, it is more easily wet, dry, and comfortable. It is very soft and excellent in pendency.
– Wide application: Hollow polyester staple fiber is a high-quality material for high-grade fabric. Blended with cotton, wool, and viscose fiber, it is widely used to make thin thermal underwear, warm winter casual wear, and sportswear with good warm-keeping, soft feeling, and soft luster. It is also used to make soft and thermal socks and gloves with wear resistance. It is also used to make light and soft tweeds.

Recycled Polyester Staple Fiber Production Process

What is Hollow Conjugate Fiber? 

Hollow conjugate fiber means a conjugate fiber maintaining a hollow form

The hollow form that does not fill the section of the fiber and the 3D crimp from heterogeneous polymer provides excellent bulkiness and elasticity and makes light and warm fibers. The lineup includes a product with extra soft feeling obtained through special silicon processing and a product featuring flame retardant property and slick touch through special oiling agent processing.

Three-dimensional crimped fiber is called a spiral three-dimensional crimped conjugated polyester fiber.

Polyester’s wrinkle resistance and heat resistance are superior to other fibers, and its UV resistance and impact resistance are better.

The three-dimensional crimp fiber is a good option as the filling materials of home textiles, such as pillows, cushions, and sofa. The specific requirements are as following:

1. Fiber length requirements: In general, the fiber lengths include 7D, 12D, and 15D, among which the lower D number indicates longer fiber length, finer fiber fineness, as well as better warmth-keeping ability, fluffiness, and thickness. Fibers of 7D or less are the best options for filling materials.
2. Fiber shape requirements: In general, there are zigzag-shaped and spiral-shaped fibers. Among these two, the spiral-shaped fibers are better due to their higher saturation force and elasticity, more space between fibers, as well as better warmth-keeping ability and fluffiness.
3. Fiber structure requirements: In general, there are three types of fiber structures: regular structure, single-hole structure, and porous structure. If the structure of fiber contains a single-space with a certain length, the fiber is called hollow fiber. On the other hand, the porous structure contains four to seven spaces.  Due to different structures, filling fiber is different in its appearance and texture. Their warmth-keeping ability, fluffiness, and elasticity also vary
